Hey Everyone, 

I have been driving for dollars in my neighborhood and I came across a vacant house in a fairly nice neighborhood. It is a fixer for sure......there's a mountain of garbage by the side of the house and when I got to the door, there wasa sign from the city stating the house. Is condemned because there is no power or water to the house.  The main structure  looks in good shape though. 

So here is my question, on the notice is also the owners name and address which is about ten blocks away. do you think I should go knock on the door?.....send them a letter? Or work on getting their number to call them?  OR... all of the above?.....also. A list of some good questions to ask them would be awesome as well.

Thanks
